Another posting of an Ostrich

Common Ostrich is a large bird which doesn't fly. It is the largest bird living in the World.
Male has black glossy plumage, with supple feathers on back. Primary and tail are white, making it easily visible.
Female and young have brownish feathers instead of black, allowing them better camouflage.
Male and female have bare neck, as the legs. Skin is blue or pink in male and pinkish grey in female. They have a long and moving neck, a small flat head, large eyes with long black lashes, powerful whitish legs with two toes. Flesh colour bill is wide.
Common Ostrich lies down on the ground, extending its neck in the extreme. This particular behaviour is maybe at the origin of the rumour saying that the ostrich hides its head into the sand, from where the expression "to make the ostrich" when one wants to be unaware of outside...
While feeding, Common Ostrich frequently raises the head in order to watch over the surroundings. Not having teeth, it swallows pebbles which help it to crush food in its sinewy stomach.
Common Ostrich is not very gregarious and lives alone or in groups of 5 to 50 individuals and we usually find it with antelopes and zebras. Each group occupies a territory from 2 to 15 squared km during the breeding period which lasts approximately 5 months. Its powerful legs are its only defence against its natural enemies. If threatened, it can give vigorous blows. It has keen view and hearing, which make it able to detect a predator, even at some distance.
It practises the dust bath, like the other birds, but it likes water and bathes each time that it gets a chance to do it. It can survive for long periods without drinking. It can also resist to a loss of 25% of its weight by dehydration.Its feathers are used as insulator against the sun, but also to provide shade to the chicks.
Male can have from 2 to 6 females. Once divided into breeding groups, Common Ostriches use community nests being able to receive from 15 to 60 eggs.
Common Ostrich breeds during the dry season. Male prepares several depressions in the ground, by scraping sand on its territory. It chooses the nest-site
and several females copulate with it.
Each female lays 2 to 11 cream-coloured eggs, weighing more than one kg each one, in the community nest. But only dominant male and female guard the nest.
Dominant female sits on the nest during the hotter hours of the day, male replacing her at night.
In spite of the constant survey of parents, less than 10% of the eggs will give birth to chicks. They are rusty coloured with dark brown spots and a "shawl" of fluffed down on back. They leave the nest a few times after hatching. They reach the adult size at one year and half, and their sexual maturity at the 2 to 4 years of age.

Hoi Vivian , Prachtige foto leuke compositie mooi licht en bg , groeten teunie .

Dear Viv

I am so intrigued by this interesting bird and it is always a pleasure for me to search information about and look at pictures of them.

Have you seen the cute baby ostrich posting that Loot has posted and dedicated to all the females of Trek Nature?
I have always just seen grown ostriches, and this was a first to me. A real interesting bundle of feathers.
Please do yourself a favour and go to the link I have included. Junior, sure is a cutie, and too adorable for words. I am sure you will love it.

I must say that I am not a great critiquer but I do enjoy an interesting note or information about the subject which make one appreciate it more.

Because I am not a photographer myself I love to look and learn via all the beautiful photos posted on Trek Nature. I just admire the talented people who do not mind to share their photographic experiences and knowledge with uninformed people like myself.

Kind regards
